Description

kernel_interface.c:update_sa resets the ESP sequence numbers, which is not interoperable with hosts other than strongSwan. Either use XFRM_MIGRATE (which is not available on all kernels and lacks encapsulation update) or better manually migrate ESP sequence numbers.

History

#1 Updated by Tobias Brunner about 14 years ago

we use XFRM_MSG_GETAE and XFRMA_REPLAY_VAL to manually copy the sequence numbers (this requires a kernel version of at least 2.6.17).
